SPECIFICATION forming part of Letters Patent No. zemeeofeatea April 29, 1884-.

Application filed October 19,1882. (No model.) Patented in England October 2-2, 1879, No. 4,278; in France April 20, 1880, No. 136.230,

.To all whom it may concern Be it known that we, J OHN HORROOKS and JAMES HORROCKS, citizens of Great Britain, residing at Manchester, in the county of Lancaster and Kingdom of Great Britain, have invented certain new and useful Improvements in Machines for Doubling and Winding Yarn or Thread upon Bobbins; and we do herebytional contact of the bobbin with the periphcry of the driving-drum; and it has for its object to automatically stop the rotation of the bobbin by causing it to be lifted off the driving-drum when one or more threads break or are absent, so as to enable the attendant to find the broken or absent thread end or ends and tie the same.

The invention consists, essentially, in the combination, with the bobbin and the detectorplate, of appliances to automatically lift the bobbin out of contact with the driving-drum,

and for removing the detector-wires out of the path of the angular shaft when one or more of said wires fall into the path of said shaft on the breakage or absence of athread orthreads; and it further consists in the construction of the detector-plate substantially as hereinafter described, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation illustrating two constructions for carrying out our invention. Fig. 2 is an elevation, partly in section and on an enlarged scale, of the mechanism employed for carrying out our invention, and shown on the right side of Fig. 1. Fig. 3 is a plan View of the same. Figs. 4;, 5, 6, and 7 are detail views of the detectorplates. Fig. 8 shows a construction of supporting-bracket for the bobbins of a double machine when the mechanism 'for lifting said bobbins out of contact with the drivingdrum is the same for each bobbin. Fig. 9 is a plan view; and Figs. 10 and 11 elevations of the mechanism shown on the left of Fig. 1, the latter view showing the bobbin out ofcontact with the driving-drum. 5 5

In the above-described figures of drawings like letters of reference indicate like parts.

A is the frame,of suitable material and construction to support the operative mechanism. Various constructions of mechanism may be adopted in carrying out our invention, and to better illustrate the same we have shownv two such constructionsone on the right and one on the left side of the frameeither one of which may be employed in a single machine, or both may be employed in a double machine, or the one or the other mechanism may be duplicated on opposite sides of the driving-drum in a double machine.

In order that our invention may be better understood, we will first describe the mechanism shown on the right side of the machine for automatically lifting the bobbin out of contact with the driving-drum whenever one or more threads break or are absent, which mechanism we prefer to use in practice.

Referring to the mechanism shown on the right of Fig.1 and in Figs. 2 and 3, as well as to Figs. 4, 5, 6, and 7, the spindle h of the bobbin H is mounted in bearing-grooves b formed in the outer end ofthe side bars, I,of a frame, L'that is mounted upon a shaft, z, to one of which side bars is pivoted a prop, I, that serves to hold the frame up when the bobbinisliftedoffthedriving-drumO. Theshaft 8 I 'i has its bearings in standards or brackets i, secured to a beam, A, of the main frame A. A lever, D, the forward end of which is or may be slightly bent upward like the outer end of a similar lever, hereinafter described, is pivoted in standards d, secured to beam A, and said bent end of the lever lies underneath the bobbin H. The rear end of the lever has a handle, D, and carries the bent wire D, hereinafter described, that is adapted to rest 9 5 upon the horizontal wire 6 of the detectorplate. I p

G is the angular or ratchet bar, by means of which the detector-plate is tilted when athrcad or threads break or are absent, to release the lever D and lift the bobbin out of contact with the driving-drum.

The frame I is automatically returned to its normal position when the lever D is raised to place the bent wire D upon wire 0 of the detector-plate by means of an arm, (1, projecting laterally from the lever D, which arm (1 as the lever D is raised, comes in contact with the prop I, that serves to hold up the frame I, and pushes the lower end of said prop to one side, allowing the frame I to fall and bring the bobbin in contact with the drivingdrum. In this construction, after the bobbin has been lifted out of contact with the drum and its momentum arrested by the lever D, the attendant tilts the frame until the prop I rests upon the beam A, thus enabling him to more readily rotate the bobbin to find and tie the broken or absent threads.

The pivoted detector-plates are constructed with three ribs, 0, that limit the movement of the detectorwires E. In said ribs are formed as many notches or grooves 0* as there are de tector-wires employed, and said detector-wires are bent, as shown at e", to prevent their being lifted out of the grooves and also to prevent their rotation in said grooves and limit their downward movement when a thread breaks or is absent. The wires are held in the grooves by means of a plate, E", which may be securely fastened to the detector-plate either by foru1- ing lugs on its opposite ends, under which the plate may be slid, as shown in Fig. 6, or said plate E may be attached to the detector-plate by means of a screw, 0, and a thumb-nut, E, as shown in Fig. 5.

The threads to be doubled or wound are drawn from cops or from bobbins or swifts arranged in any ordinary manner. Said threads pass each through a slit in a cleaning or guide plate, K, and over a flannel-covered tube, L, to give friction and clean the threads. From the tube the threads pass through the guide hooks or curls 0" of the detector-wires E,thence over the pulleys M, mountedinbearings formed in arms m, secured to the upper cross-head, A, of the main frame A. From the pulleys M the threads descend through guide-loops n, adjustably secured to a bar, N, that has the usual traversing motion for distributing the threads, from which guide-loops said threads pass onto the bobbins, all as plainly shown in Fig. 1. Should, however, one or more of the threads break or be absent, the detector-wires thereof will fall, and their ends project below the detector-plate into the path of the angular shaft G. The latter in its rotation will strike the projecting ends of the wires and tilt the detector-plate forward, thereby mov-. ing the wire 0 from under the bent wire D and tripping the lever D. The outer end of the lever in its upward movement will carry the bobbin 1) with it and hold the same out of contact with the driving-drum, the lever at the same time arrest-ing its momentum. The

wire D, in passing behind the wire 0, draws the detector-plate E toward it sufficiently to move the projecting ends of the detector-wires out of the path of the angular shaft G. By tilting the frame a little farther upward, the prop I swings to avertical position, its lower end resting upon the beam A, thus holding the frame and bobbin clear of the lever and driving-drum, and thus enabling the attendant to rotate the bobbin and find and tie the broken or absent thread or threads. \Vhen this has been done and the lever D is lifted again into its normal position, the arm (1 pushes the prop I" from under the frame I, which moves downward and again brings the bobbin in contact with the driving-drum.

The mechanism is operated from any suit able prime motor through the medium of the driving-drum shaft, which carries a pulley or pulleys (according as the machine isa single or double one) belted by crossbelts to a palley on shaft G. (Shown in dotted lines, Figs. 10 and 11.) \Ve have deemed it unnecessary to show this mechanism in detail, as any mechanic at all familiar with this class of machines will readily be able to properly apply and operate the same.

Having now described the mechanism preferably employed by us, we will now describe a modification thereof, which differs but slightly in construction and operation, said mechanism being shown on the left of the machine.

13 are inclined guides formed on or attached to brackets B, secured to a carrier-beam, B-. V hen a double machine is made with both sides alike, the inclined brackets B, to guide the ends of the spindles or axes of the bobbins, are or may be made double, as shown in Fig. 8, and secured to a beam, B", passing from end to end of the frame immediately under the drum-shaft 0. One bracket, 13, guides and holds the ends of the bobbin on each side of it. Upon the bracket B is adj ustably secured, by means of aslot, b, and aset-screw,b,astandard, d, that serves as an adjustable fulcrum for a lever, D, the fomvard end of which lever is slightly bent upward, and said bent end extends underneath the bobbin when in working position, and nearly the entire length thereof, as shown in dotted lines in Fig. 2. At its rear end said lever is provided with ahandle, D, and a loop or eye, (1, for the suspension thereto of a weight, (1, if desired; or the lever may be weighted. A bent wire, D, is adj ustabl y secured to the rear end of the lever D by means of set-screw d. The end of this bent wire rests upon a wire, 0, secured in projections formed on or attached to the detectorplate D, said plates, having pivots or trunnions at each end resting in bearing-grooves formed in brackets f, secured to or cast with a beam, F, passing from end to end of the main frame A. The pivoted plate E, by its own weight and the weight of the lever D, is forced against astop formed by shoulder f on the brackets f, which hold said plate against movement in that direction. XVliemhowever,

IIO

one or more detector-wires E fall from the breakage or absence of a thread or threads, the end of the wire or'wires so falling will come in contact with ratchet or toothed wheels mounted on a shaft arranged to rotate immediately below said wires, or with a shaft or bar, G, of triangular or other angular form in crosssection, said shaft rotating in the direction of the arrows, Figs. 1, 10, and 11, and causes the detector-plate E to swing. forward, by which movement the wire (2 will move from under the bent wire D .and allow the lever D to descend by its own weight or by the additional weight (1 and its forward bent end to lift the bobbin H out of contact with the drivingdrum 0. If desired, the additional weight (1 may be suspended from the detector-plate, said plate being provided with a suitable lug projecting therefrom, as shown in Fig. 6. The bent wire D, in its descent, slides behind its supporting-wire e and tilts the detector-plate J E forward and away from the shaft or bar G.

This movement of the plate E may be increased or diminished within certain limits by a corresponding adjustment toward or away from the plate E of the standard d, or by varying the angle of the bent wire, or by the adjustment of said wire through the medium of the set-screw (1 By this forward motion of the detector-plate Ethe ends ofthe fallen detectorwires E, projecting below the detector-plate, are carried out of the pathof the rotating bar G. WVhen the bobbinH is held out of contact with the driving-drum by the lever D, which serves also as a brake to arrest the momentum of the bobbin, the attendant can raise said bobbin into bearings b", formed in the upper end of the guides B, by sliding the bobbin-shaft or spindle h up in the grooves I) of said guides B, and he may then rotate the bobbin to find and tie the thread end or ends. When this has been done, the lever D is lifted by means of the handle D, which releasesthe-detector-plate and allows it to fall backinto its normal .position, when the bent wire D may be placed upon wire 6 to hold the lower end of the lever out of contact with the bobbin, the attendant holding said lever until the tension upon the thread has drawn up the detector-wires out of the path of the angular shaft or bar G.

It will be understood that,instead of the detector-plate hereinbefore described, any other suitably-constructed detector-plate may be employed.

We claim-' 1. The combination, with a pivoted detector-plate, the detector-wires thereof, a driving-drum, O, and a rotating, shaft, G, of mechanism, substantially such as described, to lift the bobbin clear of the drum when one or more detector-wires fall in the path of shaft G on the breakage or absence of a thread or threads, and automatically carry said wires out of the path of said shaft, as described, for. the purpose specified.
